Innocent enough

This is a curious find for anyone visiting Edinburgh. I suspect it may even be on the tourist trail.
This is a photo of a railway tunnel. The tunnel can be found right next to Arthur's Seat. It was part of The Edinburgh and Dalkeith Railway, which is also called the Innocent Railway.
The photo is taken from the Northern entrance which is now somewhat hidden in a development of flats. I say somewhat hidden.... in reality, the innocent railway now forms part of a cycle path which crosses the city.

Still back-blipping some pics from my recent trip to Germany.
The latest 2 can be found here: Lovely castle and Lovely Castle 2.
